For a low priced headlamp, this is a great product. Admittedly I don't have much experience with other headlamps, but this one makes me feel like I won't need to. What you get: This headlamp ships with the headlamp itself, and a set of three lenses (Red, Green, Blue), that you can use to change the color of the light emitted. Setting it up: The Princeton Tec Quad LED Headlamp is pretty easy to set up; to install the batteries you only have to remove one screw, which you can do without the need for a screwdriver, and then insert the batteries (it takes 3 AAA batteries). Switching out the lenses is a little bit trickier, and I can't remember whether there were any kind of instructions telling you how to. That being said, it's still easy to do. Simply pry up on the little tabs which can be found on either side of the power switch (I use the tip of a knife), and swing the cover forward. You can insert whichever of the lenses you want, and then close the cover until you hear the snaps of the tabs locking back into place. Use: The headlamp has three brightness levels and a strobe function. You press once for the lowest setting, and then press once for each brightness setting increase. If you press again after reaching the brightest setting, the headlamp begins strobing. To use whichever optional lens you inserted, all you have to do is slide it up over the white LED bulbs, and when you don't want the colored light anymore, you can just slide it back down. The headlamp also tilts forward and has quite a few different degrees of tilt that you can choose from. In my experience with it, the Princeton Tec hasn't once flopped forward on me, even after several high impact landings. It stays firmly in place, no matter what angle you've got it tilted at. The headband it comes with is a very comfortable neoprene/elastic feeling band. I've worn it with and without a hat so far and haven't had a problem with it being too big or too small (I've got a pretty big head). The white light is pretty far reaching (I'd say about 50 feet, which I consider to be far reaching anyway), and bright. The lenses take a little time to adjust to since they dim the light down, but they'll help you find your way while preserving your night vision capabilities. Con: There is one con to this headlamp, and it has to do with storing your extra lenses. The package includes a little clip that you can attach to the headband, and I've found it pretty useful for storing one of the extra lenses. I'm assuming that's what it's for, since I can't find any other purpose for it. The downside is that it only holds one. So if for some reason I need to use all of my lenses in one night, I'll be able to quickly switch out for one, but if for some strange reason I find myself needing the third, I'll have to go digging in a pocket or backpack for the tiny baggy holding the tinier lens. This isn't a big problem at all, since I don't foresee needing a red, green, and blue lens all in one night, but it just makes more sense to have them all in one place. It's not enough to knock off a star, just a mild nuisance. In summary, this headlamp is a great investment for anyone who might want to go on night hikes, play airsoft at night, or really do anything in the dark. It's definitely a more convenient alternative to a flashlight so that you can keep your hands free and still have light. It's comfortable, versatile, and very easy to use. I could open it up and install new batteries with gloves on and no screwdriver, which is a plus. Definitely would recommend, especially since it's list price is so low.
